all

Applied to a predicate and a list, all determines if all elements of the list satisfy the predicate. For the result to be True, the list must be finite; False, however, results from a False value for the predicate applied to an element at a finite index of a finite or infinite list.

alloca f executes the computation f, passing as argument a pointer to a temporarily allocated block of memory sufficient to hold values of type a.
The memory is freed when f terminates (either normally or via an exception), so the pointer passed to f must not be used after this.

allocaBytes n f executes the computation f, passing as argument a pointer to a temporarily allocated block of memory of n bytes. The block of memory is sufficiently aligned for any of the basic foreign types that fits into a memory block of the allocated size.
The memory is freed when f terminates (either normally or via an exception), so the pointer passed to f must not be used after this.

The module Foreign.Marshal.Alloc provides operations to allocate and deallocate blocks of raw memory (i.e., unstructured chunks of memory outside of the area maintained by the Haskell storage manager). These memory blocks are commonly used to pass compound data structures to foreign functions or to provide space in which compound result values are obtained from foreign functions.
If any of the allocation functions fails, a value of nullPtr is produced. If free or reallocBytes is applied to a memory area that has been allocated with alloca or allocaBytes, the behaviour is undefined. Any further access to memory areas allocated with alloca or allocaBytes, after the computation that was passed to the allocation function has terminated, leads to undefined behaviour. Any further access to the memory area referenced by a pointer passed to realloc, reallocBytes, or free entails undefined behaviour.
All storage allocated by functions that allocate based on a size in bytes must be sufficiently aligned for any of the basic foreign types that fits into the newly allocated storage. All storage allocated by functions that allocate based on a specific type must be sufficiently aligned for that type. Array allocation routines need to obey the same alignment constraints for each array element.

This is an alpha release of Allure of the Stars, a near-future Sci-Fi roguelike and tactical squad game. The game is barely fun at this stage and not yet really Sci-Fi. See the wiki for design notes and contribute.
New since 0.4.8 are screensaver game modes (AI vs AI), improved AI (can now climbs stairs, etc.), multiple, multi-floor staircases, multiple savefiles, configurable framerate and combat animations and more. Long term goals are high replayability and auto-balancing through procedural content generation and persistent content modification based on player behaviour.
The game is written using the LambdaHack roguelike game engine available at http://hackage.haskell.org/package/LambdaHack.
Version 0.4.10.5

Allocate a block of memory that is sufficient to hold values of type a. The size of the area allocated is determined by the sizeOf method from the instance of Storable for the appropriate type.
The memory may be deallocated using free or finalizerFree when no longer required.

Allocate a block of memory of the given number of bytes. The block of memory is sufficiently aligned for any of the basic foreign types that fits into a memory block of the allocated size.
The memory may be deallocated using free or finalizerFree when no longer required.

Allocate some memory and return a ForeignPtr to it. The memory will be released automatically when the ForeignPtr is discarded.
mallocForeignPtr is equivalent to
> do { p <- malloc; newForeignPtr finalizerFree p }
although it may be implemented differently internally: you may not assume that the memory returned by mallocForeignPtr has been allocated with Foreign.Marshal.Alloc.malloc.
GHC notes: mallocForeignPtr has a heavily optimised implementation in GHC. It uses pinned memory in the garbage collected heap, so the ForeignPtr does not require a finalizer to free the memory. Use of mallocForeignPtr and associated functions is strongly recommended in preference to newForeignPtr with a finalizer.

This function is similar to Foreign.Marshal.Array.mallocArray, but yields a memory area that has a finalizer attached that releases the memory area. As with mallocForeignPtr, it is not guaranteed that the block of memory was allocated by Foreign.Marshal.Alloc.malloc.

This function is similar to Foreign.Marshal.Array.mallocArray0, but yields a memory area that has a finalizer attached that releases the memory area. As with mallocForeignPtr, it is not guaranteed that the block of memory was allocated by Foreign.Marshal.Alloc.malloc.

Resize a memory area that was allocated with malloc or mallocBytes to the size needed to store values of type b. The returned pointer may refer to an entirely different memory area, but will be suitably aligned to hold values of type b. The contents of the referenced memory area will be the same as of the original pointer up to the minimum of the original size and the size of values of type b.
If the argument to realloc is nullPtr, realloc behaves like malloc.
